Product Description
Low Speed Steel Roller Bearing Spherical for Deceleration Device 21308-E1-K AH308
Description:
Spherical Roller Bearing Low Speed Heavy Load 21308-E1-K assembled with Withdraw Sleeve AH308
Spherical rollers are put between the spherical raceway on the outer ring and the two grooves on the inner ring for these bearings. Since the center of the arc raceway on the outer ring is the same as the center of the whole bearing arrangement ,these bearings are self-aligned and automatically adjust the bending of the shaft and housing and the eccentricity.
The bearings can carry radial load and axial load in double directions. The especial radial load carrying capability makes these bearings suitable for heavy load and shock load carrying.
The tapered bore with adapter sleeve or withdrawal sleeve makes the mounting and dismounting on the shaft quite convenient.
